Neglected Tropical Diseases in conflict-related humanitarian emergency settings: a systematic review of the literature

BackgroundNeglected Tropical Diseases (NTDs) are a group of 21 conditions affecting an estimated one billion people worldwide, causing significant mortality and morbidity. The World Health Organization (WHO) has targeted their control, elimination or eradication by 2030, whilst highlighting that conflict and humanitarian emergencies are risks to achieving this. MethodsA systematic review of peer-reviewed literature was undertaken, using terms related to conflict-related humanitarian emergencies (CRHE), based on the Armed Conflict Location & Event Data Project codebook terms for defining emergencies, and terms including all WHO-defined NTDs. After a two-stage screening process, 26 papers were included. ResultsCommon challenges for NTD programmes in CRHE were healthcare access, infrastructure, population movement and data quality. Multi-sectorial collaboration between actors in conflict-settings was offered as a learning for NTD programmes, along with community participation and decentralisation. Evidence gaps were identified in the knowledge base for certain NTDs and in high-quality evidence for interventions in CRHE. ConclusionsCollaboration is a key area for focused improvement for NTD programmes in CRHE. This should be across sectors, and extend to research and analysis approaches, to ensure the most effective interventions are identified and implemented, and NTD road map targets can be achieved.
